MECHANICAL MOVEMENT.

Specification of Letters Patent.

Application filed February 20, 1912. Serial No. 678,952. 7

Patented June 18, 1912.

To all whom, it may concern Be it known that I, TIDEMAND OPSAHL, (bornin Norway, and who has declared his intention of becoming a citizen ofthe United States) residing at Fillmore, in the county of Ventura, Stateof California, have invented new and useful Improvements in Mechanicalll lovemcnts, of which the following is a specification.

I have shown my device as it would be applied to the magneto shaft of anexplosion engine for the purpose of advancing or retarding the sparkingthereof, but I do not limit myself to such application.

Heretofore, in the operation of explosion engines, when it was desiredto advance or retard the sparking thereof, it was necessary to oscillatethe breaker boX containing the contact points and their connectingwires, which often resulted in wearing off the insulation from thewires, loosening the wires from the posts and bending the contact pointsout of alinement, thus causing the engine to frequently misfire.

The object of my invention is to provide simple and eflicient means foradvancing or retarding the sparking of an explosion engine, which willnot disturb the wires or contact, and which will be easy to operate andpositive in action. I accomplish this object by means of the devicedescribed herein and illustrated in the accompanying drawings in which:

Figure 1 is a view in elevation of my in vention. Fig. 2 is alongitudinal section taken on the line 2-2 of Fig. 1. Fig. 3 is a crosssection on the line 3-3 of Fig. 1.

In the drawings 5 and 6 are the driving and driven shafts respectively,the ends of which abut together. A coupling sleeve 7 surrounds theabuttlng ends of said shafts. A pin 8 rigidly secures said sleeve toshaft 6. Surrounding sleeve 7 and slidable thereon is an adjustingsleeve 9. Said adjusting sleeve has an enlarged portion 10, preferablyat one end, in which is out a groove 11 for the reception of anoperating collar 12. Collar 12 is preferably made in halves and isconnected together by screws or other fastening means passing throughlugs 12. An operating lever 13, the lower end only of which is shown, ispivotally connected to collar 12 and provides means for operating theadjusting sleeve. A pin 15 is rigidly sesaid coupling sleeve,

cured in and near oneend of sleeve 7 and extends upwardly into adiagonal slot or way 16 in sleeve 9.

In shaft 5 near the abutting end thereof is rigidly secured a pin 17which extends downwardly through a transverse slot 18 in sleeve 7 andthence into a longitudinal slot or guide way 19 cut in the sleeve 9.Slots 18 and 19 are shown in dotted lines in Fig. 1.

In the operation of my device with the parts in the position shown inthe drawings, should it be desired to advance the spark of the enginethe adjusting sleeve is moved in the direction of the arrow in Fig. 2,which causes it to slide to the right upon sleeve 7, thereby advancingthe application of the driving power to the driven shaft. As the drivenshaft carries the contacts which engage the terminals of the breaker boxthe spark is thereby advanced. The reverse movement of sleeve 9 will, inlike manner retard the spark.

Having described my invention what I claim is:

1. A mechanical movement comprising a driven shaft; a coupling sleevesecured to the driven shaft and projecting beyond the end thereof, saidsleeve having a transverse slot in its projecting portion; a drivingshaft projecting into said coupling sleeve in alinement with the drivenshaft; an adjusting sleeve slidably mounted upon said coupling sleeve,said adjusting sleeve having a longitudinal slot crossing the transverseslot of the coupling sleeve, and a diagonal slot opposite thelongitudinal slot; a pin mounted in the driving shaft and projectinginto the transverse slot of the coupling sleeve and the longitudinalslotof the adjusting sleeve; and means to shift the adjusting sleeveupon the coupling sleeve whereby the power of the driving shaft may beapplied to the driven shaft at different points.

2. A mechanical movement comprising a driving and a driven shaft inalinement; a coupling sleeve secured upon one of said shafts andsurrounding the end of the other shaft, said sleeve having a slottherein; an adjusting sleeve mounted and slidable on said adjustingsleeve having a slot therein at right angles to the slot in the couplingsleeve and crossing the same, and another-slot diagonal thereto; a

pin mounted in the shaft not secured to the have hereunto subscribed myname this 10th coupling sleeve and passing through said day of February,1912.
